Can e field be negative
WebThe magnetic field is a vector field, meaning that it has a magnitude and a direction at every point in space. The magnitude is never less than zero by definition, and it doesn't generally make sense to try to label some directions as "positive" and some as "negative", as it does for a one-dimensional vector (with only two possible directions).

WebAn electric field can never be negative . An electric field is a force experienced by the charge divided by the magnitude of the charge. Why are electric fields important? Electric fields (e- fields ) are an important tool in understanding how electricity begins and continues to flow. Electric fields describe the pulling or pushing force in a ... WebThe nuclei of large atoms, such as uranium, with 92 protons, can be modeled as spherically symmetric spheres of charge. The radius of the uranium nucleus is approximately 7.4×10−15 m. (c) The electrons can be modeled as forming a uniform shell of negative charge. What net electric field do they produce at the location of the nucleus?
